SOLAS would apply, but has very little to say about subsurface, as that's usually military or very specific hazardous commercial. Most rules in international waters apply via the flag you are flying, and submersibles don't need to fly a flag, as they aren't ships, per.se.

@nova @dma @quintessence @Taniwha @hazelweakly @malte awesome writeup, and the reverse proxy 'write back' was a brilliant approach.
